My first time doing this, I'd done a 10 k race the previous day with 26 runners, so the number of people arriving at Green Park tube was something of a shock!

This was well organised, the numbers and chips were sent out well beforehand and clear instructions available on the website.  

There was the usual queueing for the toilet, but the bag drop was well organised once you realised it was done on number rather than wave colours.  It was a nice touch having an A-Z area so that you could meet up with club/charity members before and after.

It took a while to get to the actual start line as there was a pinch point by the entrance, not dangerous or too crowded, but it did take a while to get through.  Once through the starting pens we well laid out and not overcrowded.  

Considering the amount of people running, it didn't take too long for the orange wave to get going (though there were quite a few from other waves - possibly delayed getting into the start).  Once we set of the race wasn't too busy, didn't really have to stop for others, though there were one or two walking early on.  

The course is great, through central London with bands and support most of the way.  There were two water stations, both well organised (lots of tables), with paper cups on the first one and small plastic bottles at the second.  It was a very hot and humid day, so we were all glad of the loud support the closer we got to the finish.  The marshals around the course were very supportive.  

The finish was also good, we received our goody bags and medals quickly, with only a very short wait for shirts.  You exit via the bag drop, so that didn't take long either.

Weather permitting, Green Park is a very pleasant place to linger.  We didn't stay too long, but there was a very nice post-race buzz going on.

I'm not massively into really large fields like this, but it would definitely consider doing this race again.
